Myinvention relates to a tamping device for use in connection with railway ties, for forcing the ballast beneaththe ties. V r

An important object of theinvention is to provide'adevice of the above mentioned character which is self-adjusting when used in connection with ties of difierent vertical thicknesses, whereby the ballast may be prop erly forced beneath such ties without necespart of this specification, and in which like- Q I 20 numerals are employed'to designate likeparts throughout the same,

Figure 1 1s a perspective view of a tamplng device embodying my invention, s'h-owingthe same in use, 25. Figure 2 is an end elevation of the same,

and, r I

provided at its outer end witha loop-handle transversely of the same. It is thus seen that ment of my invention, the numeral 5 desi'g-.

jaw 11, arranged upon the top of the arm or clamping bolt 13, to engage 'with the top of 5: the base flange 9. r The brace armor bar 18 is claims. 14, rigidly attached thereto, and extending base flange 9 and clamped thereto andwill" extend between adjacent crossties 63, in par-x allel relationto the same.

I provide a tamp-ing element which is des-. ignated as a whole by the numeral 15. 'l -his tamping element embodies a preferably straight handle 16 havi ng a transverse grip" 17. The handle 16' is provided at its lower end with an inclined portion" 18, disposed at obtuse, angle with. relation. thereto Formed integral with the inclined portion I 18 is a curvedcam portion'19' whichhas convex side extendingin an opposite direc tionto theinclined portion 18; A tampln'g head 20 is formedi'ntegral v ofthecurvedcam portion 19, as shown. p

the brace arm or bar 8 is passed under the l. Atamping device for forcing ballast der railway ties, comprising ab-race arm, means to adjustably attach the brace arm to a rail so that the brace arm will extend longitudinally ofthe cross tie, and a tamping ele--- ment having a relatively long curved cam portion to engage with the edge of the brace arm, said curved cam portion being longitudinally adjustable of the brace arm, said cam portion carrying a tamping head; the length of the cam portion permitting'the tamping element to be used in tamping ballastunder cross ties having varying vertical thicknesses.
